Cristiano Ronaldo has also entered the debate over Ramos' future, with AS reporting that the Portugal international broke off from his holiday to ring the defender and ask him stay at Real.

Ramos is widely reported to be unsettled at Real - where he has played since 2005 - and United appear to be the club best placed to prise him away from the Bernabeu.

United have already seen one bid of around £32million rejected by Real, who want closer to £50million, and now a report in the Spanish newspaper AS has claimed that the club have submitted a second offer of €60million (£42.5million).

This is also likely to be rejected by Real as they hold out for their asking price, although there are suspicions that United may be being used by the player to try and engineer a new contract in Spain.

The Spain international has two years remaining on his deal but has yet to say anything publicly about where he thinks his future lies.

In a video posted on his personal website, former United defender Rio Ferdinand insisted Ramos was going nowhere and that United should stop their pursuit of the player as they risk being embarrassed.

"He's at Real Madrid with, I think, a new contract coming up. Maybe the agent is putting [rumours] out saying he wants [to leave] so Real Madrid come back in with a bumper offer and he signs on the dotted line. Happy days."

Meanwhile, the Liverpool Echo reports that Everton are interested in taking youngster Adnan Januzaj on loan next season.

The 20-year-old fell out of first team contention last season and has been linked with moves away from Old Trafford, with Sunderland and Real Sociedad both apparently monitoring his progress.

Now Everton could have joined the pursuit of the player, although there is no suggestion that United are interested in letting him leave on a permanent basis.

Their chances could be boosted by the presence of his fellow Belgians Romelu Lukaku and Kevin Mirallas at Goodison Park, although Januzaj himself is believed to want to stay put at United and force his way back into contention.

Robin van Persie has also provided an update on his future, with the United striker being quoted in The Sun as saying his future depends on the wishes of his family.

“Next year is the European Championship. That tournament is going to play a big role in the choice I will make,” he said.

“I have to be in my best form. But most important is the wish of my wife and children.

“Whatever I do, Bouchra, Shaqueel and Dina Layla are the highest of my priorities. They have to be happy.”
